I just thought about this and, in your headcanon, what does the Foundation use for dates? Month-day-year, or day-month-year? It's an international organization, and it does use metric, but I don't remember seeing many articles using DD-MM-YYYY format.

I don't do anything special with dates, but I recently noticed both my SCP's posted so far have numbers that add up to 12 (1 + 1 + 2 + 8 = 12, 1 + 3 + 2 + 6 = 12). I think I might try to keep up that trend with future SCP's.
